The 2008–09 Oregon State Beavers women's basketball team represented Oregon State University in the 2008–09 NCAA Division I basketball season. The Beavers were coached by LaVonda Wagner. The Beavers are a member of the Pacific-10 Conference and competed in the Women's National Invitation Tournament. Oregon State finished the 2008-09 season with a 20-12, the team's most victories since the 1994-95 season.

Entering the year, OSU was selected to finish eighth by both the league's coaches and media. The Beavers were 9-9 in Pacific-10 Conference games, finishing in a tie for fourth place. The nine wins were their most wins in league since the 2001-02 season.[1] Oregon State was 13-3 in home games, 6-6 in games played on the road and 1-3 in neutral site contests.[1] Oregon State won 11 non-conference games, which is the most for a Beavers' team since the club joined the Pac-10 more than 20 years ago. Oregon State went 6-0 in the month of December, the first time the team ever accomplished that. It also marked the longest win streak for Oregon State since the 2000-01 season.[1]

Brittney Davis scored in double figures in the last 17 games straight. Of the Beavers' 32 games in 2008-09, she reached at least 10 points in 24. Talisa Rhea set the Pacific-10 Conference single-game record for three-pointers with 10 in the season opener against Sacramento State. She finished the game with 42 points, which is tied for fifth-most in school history. Rhea also had 64 three-pointers in 2008-09, the third-most in a single season. After just two seasons, she has made 131 three-pointers, which is second-most by an Oregon State player.[1] As a team, the Beavers shot .744 from the free-throw line, a school record. That surpassed the previous best, set in 2004-05, of .734.

Oregon State made its second trip to the WNIT under head coach LaVonda Wagner and the sixth since the 2001 season. The Beavers opened the WNIT with a 59-47 victory over Portland State at legendary Gill Coliseum. Advancing to the third round, they lost to New Mexico, 61-56, in Rio Rancho. All-time, Oregon State is 12-6 (.667) in the WNIT, winning it in 1980 and 1982. Carol Menken holds the school record for points in a WNIT game with 33 against Drake in 1980.[1]

Davis scored her last collegiate three-pointer with 7.2 seconds remaining to pull the Beavers to within three points, making the score 59-56. The shot, a running jumper from way beyond the three-point line, came just seconds after New Mexico nailed two free throws.[3]
